SPRING LUBRICATOR.

i Application filed January 15, 1926, Serial No 81,551. Renewed April 2, 1928.

This invention relates to spring lubrica= tors ant has for its object the production of a simple and etiicient device for spraying the lubricant directly upon the springs of a vehicle, such as an automobile and the like. Another object. of this invention, is the production of asimple and eliicient spraying device which may be attached to adesired form of receptacle containing lubricant, for forcingthe same therefrom.

Other objects and advantageso't the present invention will appear throughout the following specification and claim.

In the drawings: Figure 1 is a side elevation of the lubricator, parts thereof being shown in section. Figure 2 is a section taken on line 2-2 of Figure 1.

,ey referring to the drawings by numerals, 1 designates a receptacle which is provided with a threaded upper end 2, upon which is adapted to be threaded the threaded cap 3. This cap 3 is provided with a reduced extension .1, through which extends lubricant feeding pipe 5, this pipe 5 extending; well down into the receptacle 1 as shown in Figure 1.

The feedingpipe 5 carries intermediate its ends a. regulating valve 6 for controlling the amount of. oil passing through the pipe 5. A. spray pipe 7 is supported upon the upper end ot' the pipe 5 andextends transversely thereof, the spray pipe 7 communicating with the pipe 5 at its top extremity and extending upon either side thereof. The

spray pipe 7 is provided with a spraying.

end S and an air inlet end 9, the air inletend 9 being tapered as shown in the drawing, for the ptufposc of receiving an air hose or other air supply means. A brace 10 is secured to the feeding pipe 5 near its junction with the cap 3, and the upper end of the brace 10 eng ges the spray pipe 7 near the tapering air inlet end 9, for supporting the spray pipe 7 at right angles to the feeding pipe 5.

1h balile 11 is carried by the upper end of the feeding pipe 5 and projects vertically through the bore oi the spraying pipe 7 for about a one half of the diameter of the A ip 12 is carried by the upper end of the bame 11 and extends at right angles thereto, projecting in the direction of the spraying end 8 of the pipe7.

By means of the structure above described, it will be seen that by forcing a1r through the air inlet 9, the lubricant from the container 1 will be drawn up through the feed ing pipe 5 and will. be sprayed out through the spraying end 8 of the pipe 7. The

amount of oilor lubricant'passing through or desired oil may be used, such for instance,

the oil'discarded fromthe crank case of an engine, whichrwhen mixed with the air will constitute an eliicient lubricant for the springs of a vehicle.

It should be also understood that certain changes in mechanical construction may be employed without departing from the spirit of the invention, so long as these changes fall within the scope of the appended claim.

Having described the invention, what is claimed is: y i

A device of the class described comprising a container for a liquid to be sprayed, a

liquid supply pipe extending downwardly into ti o container, a pipe joined between its ends to the upper end of the first mentioned pipe and in communicationtherewith, the second mentioned pipe having an air inlet branch-at one side of its juncture with the liquid supply pipe and a spray delivery branch at the other side of its juncture with the liquid supply pipe, a baflie extending up wardly from the side of the liquid supply pipe at the side thereof at which the air supply 1 "such of thesecond mentioned pipe located and terminating approximately at the axis of the said branch, and transversely straight lip at the upper end of the bafi'le extending at right angles therefrom toward the adjacent end of the spray delivery branch of the second mentioned pipe anddiamet-rically of the second mentioned pipe at its juncture with the liquid supply pipe and above the upper end of said supply pipe. a

In testimony whereof We afiixour signatures.
